i think you should ask for greater clarity ( detail )
'fixed income ' MIGHT include things like term deposits , property trusts , and annuities ( and possibly bonds and notes and EFTs which focus on bonds and notes )
but 'cash' is often short-duration term deposits and other short-term financial instruments , and of course some actual cash left in a bank account
now Australian and International equities are fairly self-explanatory
but liquid alternatives ?? are they talking precious metals ( or precious metal ETFs ) maybe diamonds , pearls , or vintage wine/whisky
how about have a friendly chat to your tax accountant , and see what the implications of a portfolio managed by yourself , where you can CHOOSE to put say $500 into that junior miner , newly started marijuana company , etc etc ( or maybe a couple of thousand into an ambitious large cap say FMG , MIN , WES or one of several others )
cheers
